| Abstract: | By means of the theory of thermoelasticity,the sunshine thermal effect problem of cylindrical concrete hollow pier is analyzed,the elasticity theoretical solutions to the thermal stress distribution of the pier are derived,and corresponding formulae for calculating the pier top thermal displacement are developed.Compared to the conventional calculation methods,the solutions developed in the paper are more precise,and simpler and easier for calculation. |
